I tried a 2.0 amp USB car charger and the factory cable.. .my battery got really hot and didn't charge at all.. .not sure why but the 1.0 amp charger seems to work the best...I have seen a 5.0amp at Walmart in the car department.. .but I don't feel like experimenting with that

Samsung smartphones and Tablets charge in std mode (Charging USB) unless the two data wires are "shorted". (I have seen it done directly in a high speed charge only cable or in the Samsung chargers. Some say they use a resistor.) When the data pins are "shorted", Samsung switches to high speed charging. (Charging AC). I have been harassing a factory overseas for a dual car charger (2100mA) with one std. Port (iPad) and one Samsung port. It should be available soon.

In my opinion... I have wasted alot of $ on trying to get away cheap on a car charger. By far the best one is the official verizon one. It charges to 100% from 0 in less than 2hrs and charges while I am navigating, wifi tethering and using bt at the same time. Well worth the extra cash.

I haven't tried another car charger personally, but can vouch for the Verizon one. Always works for me and I just leave it plugged in the lighter outlet in my center console so whenever I need it, it's easy and quick to plug in the phone. Also has the scrunchy style cord to keep things neat. But at the same time, it makes it more difficult to use the phone while it's plugged in as it keeps wanting to pull back lol
